63 MERC.1000 REBUILD?

[mudrow]

I have a merc. 1000 100hp inline 6. Wanted to know if it is rebuildable. Have checked comp. Top two cyclinders are way below the others. 60&70 on top two, 120 on others. Looks like someone has messed with the gasket on the head, may be leaking there. If other problems like scored cyclinders can I bore it out(oversize) and get pistons. Checked parts on Bam Marine but only standard size pistons. They have most other parts as well. $128 for one pistons there. I can do most work myself but dont have mic guages. Any help or advice. New manual on the way.

mudrow, it depends how bad the engine is inside take the port covers off and look at it. Its a old engine but that makes it very forgiving as far as cyl. taper and out of round. You may be able to find a parts engine at a marine shop in your area for less than the cost of a pistion. If the cyls. aren't scored you can ck them with a piston and feeler gauge, not the most accurate but it will tell you what you need to know. Take a look before disassembly that will tell alot---Bob
